Protein Deficiency and Hair Breakage: Understanding Structural Loss
Explore how inadequate protein weakens keratin structure, leading to fragility and breakage.
Source: Journal of Dermatologic NutritionPublished on: January 31, 2025
Abstract in Plain English
Hair is more than cosmetic—it’s protein architecture. A 2025 review in Journal of Dermatologic Nutrition analyzed how insufficient dietary amino acids affect keratin assembly and mechanical strength.
Key Findings
- Participants with low serum albumin had greater hair shedding.
- Deficient methionine and lysine restricted disulfide bond formation.
- Structural microscopy showed rough cuticle edges and splitting.
- Reintroducing balanced protein restored elasticity within three months.
Why It Matters
Adequate protein intake is foundational for strong hair. This study translates nutrition science into practical evidence for preventing breakage through dietary habits.
Study Limitations
This review analyzed existing studies and did not conduct new experiments.
